Abstract

This research was motivated by the low learning outcomes of students at SMP Reformasi Plus Noelbaki and the deficient of teacher creativity to design learning related to learning models and media that are appropriate to students' conditions. Therefore, this study aims to improve the learning outcomes of class VIII students of SMP Reformasi Plus Noelbaki in relation and function material through the application of the Problem Based Learning model assisted by video animation. This type of research is classroom action research which is carried out in two cycles and consists of four stages, namely planning, implementing, observing, and reflecting. Data collection techniques in this study were observation, tests, and documentation with the research instruments being test questions and observation sheets. Data analysis techniques are descriptive qualitative and quantitative. The results showed an increase in cycle I to cycle II, that were learning outcomes increased by 38.09% to 90.48%. The implementation of teacher observation increased from 66.67% to 78.82%. The results of observations on student activities increased from 62.5% in cycle I to 83.03% in cycle II. So that, it can be concluded that student learning outcomes increased after the implementation of the Problem Based Learning model assisted by animated videos at SMP Reformasi Plus Noelbaki

Abstract

This research aims to develop mathematics learning media based on an Android application using PowerPoint and I-spring Suite on Quadratic Equations material for class IX students at SMP Negeri 1 Bola that is valid, practical and effective. The method used in this research is Research and Development (R&D) using the ADDIE (Analysis, Design, Development, Implementation, and Evaluation) development model. The research results show that the learning media developed meets the feasibility criteria of being valid, practical and effective. The average total validity by material experts is 4.60 and media experts is 4.57 in the "valid" category. The average total practicality of the small class students' responses was 4.28, and the main class students' responses were 4.25 and the average total practicality of the teachers was 4 in the "practical" category. The percentage of student learning completeness in the small class trial was 71% with the "effective" category and the main class trial was 85% with the "very effective" category
